The () function causes abnormal program termination to occur, unless the signal SIGABRT is being caught and the signal handler does not return.

Any open streams are flushed and closed.

The abort() function is thread-safe. It is unknown if it is async-cancel-safe.

The abort() function causes a report to be generated by Crash Reporter. If you wish to terminate without generating a crash report, use exit(3) instead.

The abort() function never returns.
